Uriglnal application filed February 10,1921, Serial' No. 443,911.'Divided and this application filed November 2, 1921.

To all whom `t may concern:

Be it lmown'that we, (l) Piorn Nniwiii` iiowsiri and (2)TOMASZHALAGANDA, (l) a citizen ot the United States of America, and (2)a citizen ot Poland, residing at Omaha, in the county of Douglas andState of Nebraska, have invented certain new and useful Improvements inDirection Indie catoi's, ot' which the following is a specilication.

February 10, 1921, upon direction indicators, terminating in PatentNo.1,409,883, dated Marclrll, 1922.

One objectot the-invention is to simplify the operatingmechanism `otsignals of this character sothat by the special manipulation of a singlemember, the indicator niember may be extended and swung to the right orto the Vleft at will.

A further object of the invention is to providean improved constructionwherein the manipulation of the operating member orhandle willcontrolcircuits to illuminat` ing means Aand an audible signal when the" signalmember isentended.

`Still another Object of. the invention is to provide an improvedguiding means for the operating member or' handle for limitingmoveinentot the latter' to the proper distance when operated 'forswinging the signal member to the right'or to the left, or whenreturning it to its Vnormal intermediate position, as well as forproperly limiting requirements for a serial No. 512,253.

`successful commercial use.V g I Vvlith the above general objects inview and others that will appear as the nature of the invention isbetter understood, the same consists in the novel forni, combination andarrangement of parts hereinafter more fully described, shown in theaccompanying draw ings and claimed.

Referring to the drawings in detail, the numeral 5 designates atiame orcasing through which extends an upright rotatably mounted tube 6, theAlower end of which has a spur pinion 7 keyed thereomthe pinion 7 beingVarranged within theI casingg and meshing withy av relatively largespur` gear 8 which'is rotatably'mounted :in the casing "5 and which `isprovided with a rigid stub shaft 9 which projectsdownwardly throughthebottom wall ot the casing 5, anoperating member or hand lever 10`being pivoted atV y its forward end as at 11 to the lower end ot saidstub shaft 9, for vertical vswinging' movement. vThe pinion 7` preventsdo`w11- ward movement of the tube 6 4through the casing 5, and nuts121er the like are pro? vided on the tube 6 so as to prevent upwardmovement ot the same relative to the casvr ing 5.

Passing through a longitudinally entendlit) ing elongated slot 13 in theupper portion of tube 6 is a vertically slidable ear 14 which, incombination with the fixed lug 15, is pivotally attached to a system otsimple levers, forming an extensible lazy tong arm 1G to whichlongitudinal movementis iin-- parted by means ofi a tubularrod 17 whichhas the ear `1l 'fixed to the upper end thereof, and which is actuatedvertically by the hand lever 10. A hand 1S 'for pointing direction, isattached to a transverse bar lor plate 19, and the latter is connectedby suitn able pivot `pinsto the outer elements oi' the extensible arm16, onelpivot beingfixed as at 2O and the other being slidable in theslot 21 ot the plate/19. The handle 10 and tube 17 are normally helddepressed or lowered by means ofa compression spring 22 which isarranged within thel tube (S between an abutment 23 which is xed' in theupper end portionl otsaid tube, and the uppeiI end or. the tubular 'rod17, whereby the lazy tong arm 16 is normally held in collapsed conditionwith the hand retracted.

lThe tubular rod 17 has a slot rod Q11 extending therethrough and fixedtherein, said rod 24 being extended upwardly beyond the upper end of therod 17 and through the spring 22 where it terminates normally in spacedrelation to the central contact ofan incandescent lamp 26 which issuitably removably tixed in the upper end of the tube 6. The rod 24 issuitablyinsulated as at 27 from the rod17, which in turn is insulated,with the spring 22, from the tube G by the sleeve Ga which is formed oi'insulating material, and a` segmental contact plate 28 is suitably fixedto thevprojecting lower end of the rod 24 so as to be insulated trom thelower endV off rod 17 by the lower projecting end of the insulation 27andto be engaged by the arcuate plate 29 whi-ch is fixed to the handlever 10, when the latter is in any of? its horizontally swungpositions, whereby upward movement of said hand lever willcausesimultaneous upward inovement'of the rods 17 and 2a when said hand leveris in any oflits said positions. The shell of the lamp 26is inelectrical connection with the tubel 6, and also with the `casing 5, onewall of'which is provided with a grounded binding post 30.` rlhe bindingpost 30 is electrically connectedby means off a wire 31 to'one.contactfSQ of a switch, the' other 'contact 38 of said switch beingconnected to one side of a battery 34: whose other side is connected bymeans of wire- 85 with the binding post ot' a yieldable `contact arm 37Vwhich is insulated from the casing 5 as at 38 and'which is arranged in'the' path of the plate 28 so as to be engaged by the latter when therod 17 is elevated a sufficient distance. It willthus be seen that whentheA contact 33 is engaged with the contact 32, and the rods 17 and 2eare elevated so as to cause engagement ot plate 28 with contact 37 andengagement of the upper end of rod 211 with the central lamp contact 25,a circuit will be completed :tor lighting the lamp 2G simultaneouslywith the extension of the arm 1G, as i's`desirable at nighttime forilluminating the signal hand 18. he rays 'from the lamp 2G maybereflected toward the hand 18 by means oi suitable reflecting hood 39which is pre'l'e Laby detaehably mounted upon the upper end of the tube6.

Another spring contact, similar to the contact S7 and indicated at 110,is insulated Yfrom the casing 5 as at L11, and is provided with abinding pest 42 which is connected by means ot a wire i3 with one sideof an audh ble signal such as horn all, the other side of said signalbeing connected with the wire 31, and the contact 10 being arranged withits free end portion directly above and normally in slight spacedrelation to the tree end port-ion el the cont-act 37. Thus, when theplatel Q8 is sufficiently elevated, the lamp 25 will not only belighted, but the contactsll" and ett) will be engaged with each otherfor closing thev circuit to the audible signal and thereby callingattention ot pedestrians and the like to the intended change indirection indicated by the hand 18.

As shown in Fig. 7, theihand 18 may be constructed so as to offer littleresistance to the wind and so asto have av conspicuous and ornamentalappearance, by stamping the. samev trom sheet metal to provide nninerousrelatively large openings or pei-fiorations 18 therethrough and byproviding the lingers with colored borders as at 45, special openings t5being` provided to have the appearance of the finger and thumb nails ofthe hand.

A vertical plate-#17 is fixed to the rear of the casing 5 so as toproject above and belowthe latter, and this plate is formed with a topflange i8 through which suitable fastening devices may be passed torrigidly mounting the device as indicated in Fig. 1 in front of thedrivers seat sufliciently midway between the sides of the vehicle andwith the tube 6 extending upwardly of the wind shield A ot the vehicle,the hand lever lOlbeing disposed adjacent the dash of the vehicle withinconvenient reach of the operator. The plate 47 has a substantiallyE-shaped slot 19 formed therein, with the back portion of the E-shapedslot horizontally'disposed adjacent the lower edge of the lplate 17 andwith the legs or arms ot said slot extending upwardly. The shank oit thehand lever 10 projects through this slot 49, and it will thus be seenthat said lever will be effectively guided and limited in movement forproper manipulation ot the signal. 1n other words, when the llO leverl() is disposed in its normal position `as shown in Fig. 5, the operatormay raise said slots into which the lever will nor` inally automaticallyseat for preventing accidental horizontal swinging movement olE thesignal arm. Upon swinging the lever l() to the right, said lever willcause rotation of the'gear 8 toward the lett and this will canserotation oic the tube G and signal arm 1G to the right by transmissionor the motion from gear 8 to tube 6 through pinion 7. On the other hand,if the lever 1t) is swung to the leit, similar swinging movement isimparted to the arm 16. ln this way the arm may be swung either to theright or left" as desired, for indicating the drivers intent to turn ineither one out these directions, and as soon as the arm has been swungto its desired position, it can be imniediately extended by furtheriiianipulation of the saine lever 10 by swinging the saine upwardly. Theoperation of. the device is thus exceedingly simpliiied and improved asa plurality of controlling members i'or performing .these twofunctionshave been `employed heretofore as in the above mentioned patent at and21.

lt will, of course, be understood that the arm 16 may be extended duringthe day time by simply moving the lever 10 upwardly a slight distance,without causing contact between the plate 28 and yieldable contact 37 soas to avoid lighting ot' the lamp 26 at suchV time. Y y

As the several operations of the device and the general manner ofemploying the` construction as a drive signal have been dealt with indescribing the structure of the invention, it is believed that theconstruction and operation ofthe invention as well as the advantages ofthe same will bev readily understood and appreciated from the foregoingdescription by those skilled in the art. i Y l `What is claimed as newis:

`ln a vehicle direction signal, a rotatable upright member, anextensible signal arm carried by and rotatable with said upright member,a vertically movable element carried by the rotatable member andoperatively connected to the extensible arniso to cause the latter toextend upon slid ing movement of said element, a single lieveroperatively associated with the sliding element of the lever will causehorizontal swinging movement of said extensible arm, whereby verticalswinging movement of said lever will cause sliding of the slidableelement for entending said arm, means to prevent accidental swingingmovement of the lever when the extensible arm is collapsed and when saidlever is in either of three predeterminedv different horizontally swungpositions, means to prevent vertical swinging movement of the leverexcept when the lever is in said predetermined po sitions, a lamparranged to illuminate said signal arm, means including a circuit closercarried by the slidable element 'for lighting said lamp upon upwardsliding movement ofthe sliding element, an audible alarm, and meansincluding a circuit closer operable upon further. continued upwardmovement Lrei 'ri iv-, ri it nhercb horiyontil swinging no e soi of thesliding element for causing operation o'f said alarm. l

In testimony whereoi: We affix our sig natures.
